Under one proposal, Metro would stop running trains at 10 p.m. on Sundays and at midnight on all other nights. Another scenario calls for stations to close as early as 11:30 p.m. on weeknights and midnight on Fridays and Saturdays. A third scenario would close stations at 11:30 p.m. on weeknights and 1 a.m. on Fridays and Saturdays.

Opening times remain the same in most of the scenarios, but stations would open at 8 a.m. Sundays under the third scenario.

Prior to the start of the SafeTrack repair program, the rail system was open until 3 a.m. Friday and Saturday nights, and until midnight all other nights. Since SafeTrack repairs began in June, the system has closed at midnight every night to allow crews more time to work on the tracks. Those closing times were expected to be temporary.

"The additional track time increases safety and reliability by giving workers the time and space they need to keep Metro's infrastructure in a state of good repair," Wiedefeld said in a statement back in July.

But business leaders and riders are concerned the plan will have negative consequences.
